Overview

A 9-day-old male neonate was found to have a systolic murmur during a routine follow-up for skin jaundice. Imaging revealed a large mass at the bifurcation of the main pulmonary artery, causing significant bilateral stenosis. The patient underwent emergency surgery due to critically compromised pulmonary blood flow. Intraoperative exploration demonstrated a large ductus arteriosus aneurysm (DAA) with extensive thrombosis. The DAA was completely resected under deep hypothermic circulatory arrest, followed by reconstruction of the descending aorta and repair of the pulmonary artery bifurcation defect. The patient was discharged on the 20th postoperative day and remained asymptomatic at the 3-month follow-up, exhibiting normal growth and cardiac function.
